Firstly allow me to apologize if this is the incorrect area to place this message.
I have been trying to find a way to print a model with a very thin wall thickness eg 1-2mm. I use Rhino for all modeling needs which has an option ( Offset Surfaces) to produce objects with a specified wall thickness as desired. Of course that would be too easy. My problem is due to the busy surface contours on the model, the final output produces surfaces that are conflicting, overlapping or collapsing on each other and it would take days to manually select and repair these areas.
So, using a model of a 'cube' to experiment for time saving and simplicity, I removed one entire surface, exported the mesh model and sliced it with S3D (V5.02) and selected an Outline Perimeter of 3-4 to give a thin wall thickness. Looks great so far. I go to the next stage 'Prepare to Print" and still the 'sliced' model looks correct. (I have also tried tweaking Surface Normals to see if any difference occurs, but no.)
Problem 1 is....no matter what method I use, S3D replaces the missing/deleted surface so as to close the object. I get this.
Problem 2 is....I tried using Cross Section and the sliced model looks OK. However I end up with the same result. The printer produces a fully enclosed model.
I have added some pics that will hopefully provided a clearer understanding of what I am trying to achieve. No doubt there will be a simple method to this problem. I have been using S3D since Ver3.0 so I have much experience in that regard.
Anyhow if anyone can provide a solution or valid suggestion I would be extremely grateful.
Thanks in advance for any assistance.
